Max 2009 renders only one frame and then crashes
show user profile  Janne
Hi everybody!
My problem is this...
I´ve done a visualisation of a restaurant with few architectural materials, 4 417 032 polys, 7 different mr lights, pre-generated final gather map (draft) and one animated camera, but when I try to render the whole 100 frames long timeline to jpeg sequense, max renders one frame and crashes after that. Even when I render more than one frame manually (with single frame option), it crashes. I have to restart my max after one rendering to be able to continue with next frame. Rendering time per frame is only 8 minutes, so it shouldn´t be so heavy scene. I´ve tryed lots of different things to fix the problem, but now I´m frustrated and rendering one frame, then restart, then one frame, restart, one frame...and as you might figure, it is quite annoying...And I don´t like the idea of making my scene lighter (and uglier) because of this one damn problem in this one damn scene. So helping hands and tips are most welcome!

Does it crash because its out of memory? how much ram do you have? maybe look into the 3gb switch if it applies to you. it will let max use more of your memory. I did it and it works wonders.

I have 6gb of RAM and windows vista 64bit. I think vista is not supported with that 3gb switch...

Have you tried using a different file format so you know it is not the jpeg save that crashes max.

try rendering with the batch command line or backburner to automate doing each frame by hand.

I cant suggest anything logical to prevent the crashes within the file itself.
Only option to try is creating a new blank scene and merging everything from the old scene into it.

Tried batch render, tried applying bitmap pager, tried rendering in targa format, runned memory test of vista and now tryed to merge new scene with the old one. Still crashes! I watched the Task Managers performance monitor when it was rendering and cpu usage was about 97% and memory usage was about 5,59gb. It seems to be using the memory and cpu at full throttle. I don´t know is it good or bad thing, but at least now I know it is using all the memory I have and not just a half of it. I forgot to mention that I used also mr_photographic exposure control in the scene. Let´s see what´s going to happen...

I dont want to waste your time because i dont have a direct answer for you, however i do have a few suggestions you can try.

1. 6gb ram is not enough for your render. so you will have to research other ways to render this WITHOUT affecting your ram, i know vray has the ability to save its maps out so you will never use all your ram in the render, i dont know about mental ray.

2. your cpu should be at 97 all the time when rendering, thats normal, its the ram you have to watch for.

3. i know its a pain because you have 100 frames to render, but you can region render each frame into 4 parts which will allow you enough ram to do your render. however, it will be a nightmare to piece it together.

4. backburner or pay a company to render it for you over night.

5. try a lower resolution.

Other then this, i would google a way to render without using your ram - im quite sure this is your issue.

Ok. Thanks a lot to all of you. I´ll try to find the solution for the problem. Maybe I just go and buy 2gb more ram and see if this solves the problem. You can´t have too much of it and it is not so expensive these days...

My machine at home flips out when I try rendering to avi ( for quick previews ) so even if I just want to make sure the animation is correct I have to render to frames and stitch them together in after effects.

Try changing your file type that you're saving to.

Unfortunately Janne, 2gb extra wont help. Imagine it like this, if its currently taking 6gb to render 1 image file, then your going to need another 6gb for the next file. I would be looking at other renderers (other then mental ray), different rendering techniques, or just looking at how to save out your map files before you render so your not using your ram each frame.

- Have you switched on your geometry cache and final gather map cache?

Did you mean to write that?

I dont see why your saying this. I would think MentalRay would clear out any data from the last frame just before setting up for the next frame ? .

infact it must do something like that or I would not be able to render out an animation of my battersea project , thats using all my ram on each frame

Yeah, I´m using the same pre-generated final gather map in all the frames and I tryed the geometry cache too, but still no luck. And checked inside my computer and it was nice and clean. And about the ram...I can´t imagine the 3DS max could be piling the memory usage of the each frame on top of the earlier frames memory usage! If that would be the case, then at the frame 100, it would need about 600gb of ram, and even I don´t have that kind of money (or motherboard)
But seriously...I used lot of time and effort to get this scene to work and I´ve used mental ray rendering from the start and adjusted my materials, lighting and everything with final mental ray rendering in my mind. And there were no signs of mr renderer problems before I clicked active time segment selection and pushed render. After that...It started. Now I´ve rendered 32 frames with that render-restart-render-restart style and yes, it´s really annoying and slow, but I think it still beats modifying the whole scene again. I have my laptop still..
I think I´m going to buy that extra 2gb of ram soon as possible and post what happened afterwards!

Cheers everybody!

you're not using rpc's are you? i used to find if i had rpc people with overlapping bases it would crash a lot.
